Concept explainers
Introduction:
Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. The nucleus is bound by a nuclear membrane, and it possesses the genetic material of the cell. Cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. The plasma membrane is amphipathic, which indicates the presence of both hydrophilic (polar) and hydrophobic (non-polar) groups. Protoplasm denotes all living material that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus).
